Figure 8: PPX inhibited oxidative damage and restored antioxidant enzymes after reserpine model. DCFH (A), nitrite (B), carbonyl groups (C), sulfhydryl groups (D) levels, and activity of superoxide dismutase (SOD) (E) were measured on the spinal cord. Each column represents the mean ± SEM of six mice/group. *P < 0.05 and **P < 0.001, vs. reserpine group; #P < 0.05, ##P < 0.001, vs. vehicle group (one-way analysis of variance followed by Bonferroni’s post hoc test). DCFH: 2′,7′-Dichlorodihydrofluorescein; PPX: pramipexole.
